GAS-ENGINE ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed April 13, 1910. Serial No. 555,149.

To all/whom it may concern:

Be it known that I, LAMBERT J. B oRDo, a citizen of the United States of America, residing in Hillside, county of Montgomery,

"State of Pennsylvania, have invented a certain new and useful Improvement in Gas- Engine Attachments, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

One object of the present invention is the production of a novel attachment or fitting which is adapted to be secured in the cylinder wall of an internal combustion engine, and is formed with a passage and a transparent window closing the passage, andis provided with a valve controlling said paswhen the valve is in one position the interior of the engine cylinder may be visually observed, and when the valve is in another position the passage is closed, whereby the window may be pro tected from the pressure in the engine cylinder if desired at times of inspection and the breaking or removal of the window will not prevent the operation of the engine.

A second object of the invention is the production of an attachment or fitting adapted to accomplish the first mentioned object of the invention and having provisions for opening the interior of the cylinder at will to permit the introduction of gasolene or like-fuel for starting thp engine when cold, or, in the operation of the engine, to permit of the discharge ofa jet of burning fuel at the time of explosion in order that the manner in which the engine is functioning may thereby be determined.

The various features of novelty which characterize my invention are pointed out with particularity in the. claims annexed to and forming a part of this specification. F or a better understanding of the invention, however, and its advantages and specific obhad to the accompanying drawings and descriptive matter in which l have illustrated and described one of the forms in which the invention may be 1 "'ried out.

sectional elevation of a portion of an in- 5 the drawings, Figure l a sectional .vill be so placed that the ternal combustion engine equipped with the attachment shown in Fig. 1, and Fig. 4 is a view illustrating a modified structure which may be built up out of parts of the apparatus shown in Fig. 1.

In the drawings, A represents the cylinder wall of an internal combustion engine. In a threaded socket A formed in the cylinder wall A is screwed a bushing or hollow plug B; to the latter is secured a fitting part C As shown the fitting part G is formed with alined passages C and C extending in opposite directions from a central valve chamber C Within the valve chamber C is located a rotary valve cock D which is cut away at I) so that when the valve is in the position shown in Fig. 1, it permits of the inspection of the interior of the cylinder A through the alined passages C and O When the valve is given a quarter turn in the clockwise direction into the full line position of Fig. 3 however, it serves to close communication between the chamber C- and the valve chamber C An extension E of the fitting part G supports a window closing the outer end of the passage C? or rather the extension E of that passage formed in the fitting portion E. This window may be formed of any suitable transparent material adapted to stand up under the conditions of .use. As shown, it comprises a disk F of mica, fused quartz or the like, having its margin between washers F of suitable material, and with the washers is held in place by a hollow nut Gr screwed into the outer end of the fitting part E. As shown, the extension E is separate from the part C being provided with a threaded nipple E" which is screwed into the socket C of the port C. p

\Vith the apparatus described it will be apparent thatvwhen the valve D is in the position shown in full lines in Fig. l the interior of the engine cylinder may be visu-- ally inspected, and in particular the time .and manner in which the firing or ex plosions in the cylinder occur may be definitely determined. Ordinarily the fitting action of the igniter may be directly observed. Except when it is desired to look into the cylinder the valve I) may be in the full line position of Fig. thus normally relieving the win- (low from exposure to the pressures within nishes means by which injury to the window canbe prevented from affecting the regular operation of the engine.

Preferably, as shown, the fitting part C is provided with a lateral upturned or spout like extension having a passage G formed in it which is open at its lower end to the valve chamber C in position to be closed from said valve chamber by the valve D when the latter is in the full line position shown in Fig. 1. The channel C may be placed in communication with the channel C by turning the valve D into either of the dotted line positions of Figs. 1 and 3. When communication between the passages C and C- are established as described, gasolene or like fuel may be introduced into the engine cylinder by pouring it into the upper end of the passage C at times when it is desired to introduce fuel in this manner, as in starting the engine when cold. In'this condition of the apparatus, also, the manner in which the explosions occur within the engine cylinder may be determined by observing the character of the jets of flame issuing from the mouth of the channel C on explosion.

It is of course apparent that the fitting parts B, C and E may be made integral with each other, or separable, as shown, without affecting the operation of the apparatus as hereinbefore described. I prefer, however,

-starting when cold, and to determine the operation of the engine by watching the fire jets when explosions occur. I also prefer to make the fitting parts E and C separable for two reasons. 'One of these is due to the fact that when the parts are separable and a window disk blows out, a spare fitting part E, with the window intact, may be inserted in a few seconds. A second reason for making the fitting parts E and C separable, as-shown, is that, when trouble occurswith the fitting part 0, as in case the valve D begins to leak unduly or when it is desired to save the cost of the fitting part C, the fitting part E may be inserted directly into the bushing D, as shown in-Fig; 4.

While, in accordance with'the provisions of the statutes, I have illustrated and described the best form of my invention known to me, it-will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirlt of my invention, and

that certain features of the apparatus disclosed may be employed with advantage under some conditions without a corresponding use of other features, and I do not wish the claims herein made to be limited to the particular apparatus disclosed more than is madenecessary by the state of the art.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. An attachment for an internal combustion engine comprising a valve casing adapted to be secured in the cylinder wall of the engine and formed with a passage extending through it and directed toward and open to the interior of the cylinder, a separate part also formed with a passage through it and adapted to be secured to said valve casing with the passages in said part and casing in alinement, a transparent diaphragm secured in said separate part and closing the passage therethrough and a valve located in said casing and movable from one position in which the interior of the cylinder may be inspected through said diaphragm and passages into another position in which it closes said casing passage.
